To all whom it may concern:

EB8 it known that LELI WILmAMs, a citi- Zen of the United States, and resident of This invention has reterence'generally to improvements in vehicle wheels and more particularly relates to an emergency tread or shoe for automobile wheels.

The invention has for its primary and object the provision of a device of the above mentioned character designed to be detachably placed about the rim of a wheel, in place of a punctured tire, the purpose being to permit the driver of the vehicle to run the same to a repair station, thereby preventing damaging of the rim of the wheel.

More particularly the invention consists in the provision Of a device of the abovementioned character which is constructed in sections so that it may be quickly ap plied to and removed from position the locking means for retaining the device in position being of an adjustable nature, to

adapt the device to rims of slightly varying diameters.

It is a more specific object of the invention to provide a device of the above mentioned character, wherein improved means is employed movably and detachablg connecting the other adjacent ends of t sections of the tread together.

Among the other aims and objects of the invention may be recited the provision of a device of the above-mentioned character with a view to compactness, and wherein the number of parts are comparatively few, the construction simple, the cost of production low and the efiiciency high;

Other objects as well as the nature, characteristic features, and scope of this invention will be more readily apparent from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this specification.

The invention is clearly illustrated in the accompanying drawings in which Figure 1 is a side elevational view partly in section of a wheel showing the improved tread applied to the rim thereof.

Figure 2 is a transverse section takenon nne 2-2 or Figure l in the direction in which the arrows point, and

Figure 3 is a similar View taken on line Similar characters of reference are en1- l 'I i ployco in all ot the above described views to indicate corresponding parts. Rererrmg now more particularly to the drawings there, is provided a wheel 1 about the flanged rim 2 of. which "is detachably mounted the improved emergency tread generally' designated by the numeral 8.

With a view "toward reducingthe present invention to practice the tread is constructed of sections l and 5, preferably semicircular and formed desirably, thongh not necessarily, of wood. A-t abutting ends the section 4t is provided on its outertread surface, with a longitudinal groove 6 extending from the edge and terminating in a recess 7. A keeper plate 8 is secured to the bottom of the groove by suitable fastening means, such as screws 9, so that the inner end portion or" the plate extends into the recess 7 while the outer end lies flush with the end of the section at. The other section 5 is provided with a longitudinal groove 10 on its tread portion, said groove opening at the ad acent edge of the section 5 and arranged in alignment with the groove 6. A hooklike catchgenerally designated by the numeral 11 and formed desirably of strap metal has its inner end secured by suitable fastening means, such as screws 12 to lie within the groove 10 and flush with the outer periphery of the section. The bill 13 or" the hook is designed to lie within the recess 7 and engage the projecting inner end or the keeper plate 8, the shank portion of the hook overlying the keeper plate and lying within the groove G'so as to be flush with the outer periphery of the section t. The foregoing keeper plate and hook form the preferred means for movably connecting the adjacent ends of the sections a and 5 together so that they may be readily cennected and swung into position about the rim or removed therefrom, as is apparent.

For the purpose of providing adjustable locking means to adapt the devic for adjustment on rims of slightly varying diameters, the opposite adjacent ends of the sections are formed with transverse openings let through which are arranged suitable bolts 15, the heads of which are shaped to form respondingly threaded ear for retaining the, sections in substantially rigid relation with I respect to each other, when arranged about the rim. By reason of the threaded. portion 21 of the b0lt'20, it is apparent that the clevice is capable of attachment to rims of varying diameters, the bolt of course lying to one side of thetread and across the adjacent edges. .By removing the bolt it is apparent that the device may be T tached from the position shown.

quickly de- 7 In View of the foregoing description it is believed that a further detailed description of, the invention is entirely'unnecessary. Likewise it is believed that the advantages of the invention will be readily apparent.

" From the foregoing, it is thought that the .construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that Various changes in the size, shape, proportion and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent,-is: V

The combination with the-flanged rim of a wheel, of a detachable emergency tread composed of a pair of semi-circular sections,

a keeper plate embedded in the outer sur-' face of one section near one end, a hook-like catch embedded in theouter surface ofthe othersection and lying flush therewithand extending beyond the end edge of the section to overlie and engage the keeper plate in the 7 first mentioned section, and locking means for adjustably and detachably connecting the opposite adjacent ends of the sections together when arranged about the flanged rim of the wheel;

In testimony that I claim the foregoing I'have hereunto set my hand at In allston,

in the county of Menominee and ELI WILLIAMS.

ta-te of Michigan.
